UNITED STATES HARRY E. CAMPBELL, or BALTIMORE, 'MAR-LAD;gassioivoitffjiocAIvIrBELL vMETAI. WINDOW CORPORATION, or BALTIMOREMARYLAND,,Avooitroimrioiv' oIfYnLamr-V LAND WINDOW HEAD 'coiIsaituo'rIoN f. f j i Application led November According to the present invention, I provide a weather-tight'joint between the upper sash of a window and the lintel by forming the lintel in box-like shape, with an opening in its lower surface to receive the edge of the sash and by providing a member adjacent such opening which carries a flexible weather strip to engage the. edge of the upper sash. Such an arrangement is particularly valuable in connection with a window of the type in `:which an enlarged chamber is provided back of each j amb into which the edges of the upper sash extend, for the lintelconstruction can be carried across to the ull width of the sash so that there is a seal at the corners of the sash as well as in the part over the window opening.

Y My invention can readily be understood by .the illustrative example'herein described which shows the same applied to a type of window such as is shown in a number of my earlier'patents such, for example, as Patent No. 1,549,711, issued August 11, 1925. y

In the drawings which accompany this cated at 12 and a top plate 14. The platesv 12 and 14are bent to form glass rabbets 16. The top glass stop 18 is bent inwardly, up- Y wardly and again outwardly to form the pro jection 20, which limits the upward movement of the sash.

The side plates 12 extend through openings 40 as indicated at 22 into enlarged chambers the outer wall of which is formed by the partition member 24. The box-like lintel is formed of two members', one of which, 26, forms the inner face and al portion of the lower face which is inside of the upper sash,

and is also bent upwardly at the outside to form a Contact member 28. The other main lintel member 30 forms thebalance of the lower face, the outer :tace and the upper Vface of l v5o the lintel. Any opening is left between the that weather strip 32 seals over the. side of the 1nember'l'28 and the 'inside' edgeY of Athe bottom partofmemb'er 30 to receivetop plate 14 of the@ sash. A flexible weather strip '32 5 is slippedoverjtheftop ofportion 28 ofmember 26 'and'v is held-'in "place on"member 28l by member 30.l When'the upper sash is closed, plates`14 will strikeflexib'le weather strip 32 and deflect it'outwar'd but a tiglitl seal will be hadfbetween' thisiweather vstrip. and the plate 14. It is 'tof bejrioted, as shownA in Fig.'V 3, that portion-`28 'of member 26and the weather strip 32 both extend over toA meet partition 24 which is the outer limit of the enlarged chamber into which the side 0I' the sash extends sok sash whichis inside the jamb as well as sealing the part which is exposed when the window is open. Y

This is a very inexpensive construction to put togetherand is highly eliicient in opera tion. H What I claim is:

1. In a window of the type having jambs and openings in the inner wall of the jambs, enlarged chambers back of such openings and to extend vthrough` such openings into lsuch chambers, a hollow lintel connecting the yjambs having an opening in its lower weather-strip to deflect the sam-e away from said plate.

2. A structure Vas specilied in claim 1, in which said plateand weather strip are as long as the Width of the upper sash. 3.A structure as specilied in claim 1 in which said weather-strip embraces the upper edge of said plate and is held in place by the cover member ofthe hollow lintel.

4. A structure as specified in claim 1, in which said plate is on the room side of said lintel opening so that the tension of said 10c.

75. Y an upper sashhaving side portions adapted weather-strip will press the upper sash towards such room side.

5. In a window of the type having jambs and openingsin the inner wall of the ambs, enlarged chambers back of such openings and an upper sash having side portions adapted to extend through such openings into auch chambers, a hollow lintel connecting the jambs having an opening in its lower face l substantially in line with the opening in the inner jamb walls for the upper sash, an upwardly extending plate in the lintel adjacent such opening, a ieXible weather strip member of U-Shaped cross section looped over the l5 edge of said plate, said member being positioned so that one of its Sides is substantially in linel with the lntel opening and adjacent said plate, but said side at its lower edge ilaring away from said plate, at top portion upon said sash adapted to enter said lintel opening and sliding-ly Contact with the said weather strip member and enter between the strip and the plate whereby the weather strip member is Jforced away from the plate and the sash member is tensioned towards the plate.
